I have a 89 firebird formula 350TPI. I need the oem 2 wire plug but all I can find is the 3 wire plug. Does anyone know where I can find the correct 2 wire plug? I have looked everywhere. THANKS

Is this what you're looking for?
My plug is different than the one in that pic. That one looks like pre-86. Mine looks exactly like the 3 wire plug but mine only has 2 wires I've tried advance, autozone and rockauto with no luck.

I probably have one for you from an 89 tpi harness. I'll check tomorrow and let you know
I can buy a new 3 wire plug for $10 Cant I just leave out the 3rd wire?
I FINALLY found one in the junkyard!! Thanks guys!!
